This invention relates to an improved method of producing rear vent for unlined or skeleton garments. Heretofore unlined or skeleton garments having vents required pieces of reinforcing material on: the inner side of the 'garment, to bestitched tov the vent sections and to the body of the: garment, after which the reinforcing pieces would have to be covered by a piece of finishing material. The old method of providing vents for unlined garments resulted in the applying of strains to one of the back sections of the garment, causing ripping or tearing at the point where the reinforcing material has been stitched to the backsection. The ripping and tearing at the particular point where the reinforcing material has been stitched to form the vent weakens the garment at the particular point long before 2 the garment shows any signs of wear in other places. conditions, this invention relates to an improved method of. providing rearivents for unlined or skeleton garments without requiring the use of any stiffening or reinforcing pieces other than'a strip of finishing material made out of the lining and applied in such a way that no. strain is applied to the back sections of the skeleton garment.

It is an object of this invention to. provide an improved methodof producing a'vent in unlined garments by applying a combination reinforcement. and finishing strip .in such a manner that strains are not applied to the sections of the garment between which the vent is formed. 1 7

It is also an object of this invention to provide an improved method of producing a vent in an unlined or skeleton garment by 40 applying a finishing strip of material-on v the interior of the garment at the point of intersection of the end of a seam and the end of avent formed between sections of the the vent underlay strips and to the center seam inlay strips to causethe finishing strip to serve as a reinforcement without securing the finishing strip to the sections of the garment thereby relieving the sections of strains when pulllng or other forces are applied to To obviate the above-mentioned the sections ofthe-garment in whichthe ventis formed.

It is a further object of thisinvention'to provide an improved method of furnishing a vent in an unlined or skeleton garment by applying two garment sections, one upon the other, and bypositioning one endof a finishing strip upon one ofsaid-s'ections and then sewing the seam uniting the sections-and ineluding in said sewing one end of'the finishing strip, after whichthe seamed inlay strips are opened and theyfinishing strip is bent over the vent underlay strips, and the seamed inlay strips with said finishing strip stitched tothe inlay strips of the vent-and the seam to'reinforce the vent :at the point of inter? section of the seamand' the vent. :5 i

It is furthermore an object of this invention to provide an improved method of producing a vent in an unlined garment by withthe seam of the garment sections and then opening up the seam andstitching the reinforeingstrip to the inlaystrips of the seam and to the underlay strips of the vent section. without stitching the reinforcing or finishing strip to the sections forming the garment in which the vent is produced.

The improved method consists of placing the two garment section's-1 and 2"with the ou'ter faces thereof abutting one-another with the section 'l ly'ing uponsectionfl as-illus trated in Figure 2.

tion as hereinbefore described,the garment section 1 is now removed from beneath the garment section 2 into the position illustrated in Figure 1 and the garment ispressed along 5 the seam line 15 and continuingalong'the line 'providing a crease between the garment section 1 and the vent underlay strip 5. The reinforcingstrip 13 which covers the intersection of the garment vent with the lower end of the center seam 15 is entirely free ofathe garment section 1 so that any strains applied to the vent portion of the garment are not transferred to the garment section 1 but terminate in the strongest part of the vent reinforcement along the line 1819 where the stitching penetrates through four layers of the garment to form a very strong seam transversely across the upper end of the vent underlay sections 5 and 10.

While the invention is described as pertaining to the rear vent of an unlined or skeleton garment such as a mans coat or overcoat, it:

will of course be understood that the improved method may be applied in the forming of reinforcement at any vent provided in other portions of garments or in similar articles.

It will of course be understood that many changes may be made and'numerous details of construction may be varied through a wide range without departing from the principles of this-invention, and it is therefore not purposed limiting the patent granted hereon otherwise than necessitated by the scope of the appended claims.
